Don't know about a "definitive answer"; I've had my GS for not quite a year yet and in that time there have been a number of weeks where the car has either sat in the garage completely unused or with one 40mile trip tops.
No issues with the battery at all. When it starts the volts read fine too so no reason to suspect a lingering problem.
Hope that helps.
